What this worksheet covers
There are eighteen decimals problems here — one page to work, one page of answers to check against — and Sets B and C repeat the layout with different numbers. What makes this set particular: operands run to two decimal places, so the decimal points have to be lined up rather than the right-hand digits and the numbers run as high as 48.99. Problems 7 and 13, for instance, are "42.51 + 43.22" and "40.77 + 10.87". The sheet sits inside Common Core 5.NBT.7, in the grade 5 Number & Operations in Base Ten strand.
Skills practiced
Grade 5 decimals means adding and subtracting decimals to hundredths, and multiplying and dividing by whole numbers. Specifically, the problems practice grade 5 Adding Decimals to Hundredths. Working the page asks a student to keep the decimal points aligned.
About the drill format
A drill is straight practice: 18 problems of the same kind, laid out across the page with working space under each — problem 7, "42.51 + 43.22" is typical of the whole page. A run of one decimal operation is where point alignment stops being a decision and becomes a habit.
Set A, Set B and Set C
Set A is the original sheet; Sets B and C redraw each problem with the same shape and recomputed answers. Where Set A's problem 10 is "44.07 + 11.13", Set B's is "25.62 + 11.02".
How to use this worksheet
By grade 5 a student should take all eighteen decimals problems in one sitting. If the page takes more than about fifteen minutes, the underlying facts are probably not automatic yet, and that is worth fixing before more decimals practice piles on. Date the drill before filing it. Set C from six weeks later is the cheapest evidence you have that the decimals stuck.
